Brazilian red propolis: unreported substances, antioxidant and antimicrobial activities
(WILEY-BLACKWELL, 2011)
BACKGROUND: Chloroform, ethyl acetate and methanol extracts of a sample of red propolis from the state of Alagoas (northeast Brazil) were analyzed by gas chromatography-mass spectrometry and high-performance liquid ...
Terpenes: Natural Products for Controlling Insects of Importance to Human Health—A Structure-Activity Relationship Study
(Hindawi Publishing Corporation, 2016-08-21)
Many insects affect food production and human health, and in an attempt to control these insects the use of synthetic insecticideshas become widespread. However, this has resulted in the development of resistance in these ...

Revisiting the addition reaction of TeCl4 to alkynes: the crystal structure and docking studies of 1-chloro-2-trichlorotelluro-3-phenyl-propen-2-ol
(Elsevier B.V., 2006-11-15)
Tellurium tetrachloride adds to alkynes via two pathways: a concerted syn addition, that yields Z-tri- and tetra-substituted alkenes or by an anti addition that yields E-alkenes. The mechanistic aspects of these divergent ...

The Multiple Faces of Eugenol. A Versatile Starting Material and Building Block for Organic and Bio-Organic Synthesis and a Convenient Precursor Toward Bio-Based Fine Chemicals
(Sociedade Brasileira de Química, 2015-04)
Phenylpropenes are produced by plants as part of their defense strategy against microorganisms and animals, and also as floral attractants of pollinators. Eugenol, the main component of clove’s essential oil, is an inexpensive ...
Behavioral and molecular bases of the anthelmintic activity of essential oils explored in the nematode Caenorhabditis elegans
(Fundación Revista Medicina, 2021)
Control of helminth infections in both human and veterinary med icine currently relies mainly on chemotherapy, but acquisition of resistance is an increasing problem that leads to the urgent need of discovery of novel ...
Deciphering the molecular mechanisms underlying the anthelmintic effect of essential oils evaluated in Caenorhabditis elegans
(Genetics Society of America, 2021)
Helminths consist of a diverse group of parasitic worms including nematodes, which cause diseases of major socio-economic importance globally. Control of infections in both human and veterinary medicine currently relies ...
